NILS D. LEVIN, OF CHICAGO, ILLINOIS ASSIGNOIt TO GOODMAN MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

ELECTRIC HAULAGE SYSTEM.

To all whom it may concern:

Be it known that I, NILS D. LEVIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Electric Haulage Systems, of which the following is a specification.

The invention relates to rack rail locomotives, having for its object the providing of devices accommodating and allowing for inaccuracies between the alinementof the rails of the road-bed and the rack, which,while running parallel thereto, yet is subject to certain inaccuracies, for instance such as are due to careless workmanship, etc., it being desirable to have the propelling gear or sprocketupon the car yielding with reference to the car and so arranged as to be free to adjust itself to the differences in alinement of therack, without cam polling a corresponding inoyement of the entire truck and car. To accomplish thisin the present instance, the sprocket itself is rendered free and independent of the car or attached masses or parts thereof, by being in some way movable, swiyeling or tilting with refer-.-

Figure 1 is a side eleviition, partially in section, of a car embodying the presentinvention in one of its forms; Fig. 2 is a plan view, partially in section, of a portion of the same car, showing among other details the centrally swiveling sprocket or propelling gear; Fig. 3

' is an end elevation of the gearing in Fig. 1; Fig. 4 is a diagrammatic view of a portion of Fig. l'illustrating the plurality of guiding devices for each swiveling gear; Fig. 5'is a detail of the gear; Figs. 6, 7, 8 and 9 are alternate forms of tilting or swiveling gears, in the first three the gear hanging like a pendulum from a pivot above and the last showing a divided pivot down more nearly in the axle plane of the gear.

The motor shaft A is connected to the axle by some suitable intern'iediato gear. As illustrated in Figs. 1 and 2, for example, ihc car nxlc I; is provided with a perforated shaft or axle such the sleeve 13 through which the axle passes and carrying a bevel gear IF, which is engaged by the bevel-gear 13 connected with the inclined or oblique shaft B having one end mounted in a bearing B on a sleeve B surrounding the axle. As shown in Fig.2 the sleeve B on the front axle surrounds the sleeve B carrying the gear B while on the rear axle the sleeve B is directly mounted upon the axle at the end of sleeye B. This shaft B is connected with the gear B in any suitable manner. As shown for example in Fig. 1, this shaft receives support at its upper end through a universal joint of any of the well known constructions, in the present instance simply consisting of the double right angle knuckle, one part B engaging the gear and the other part B connected with the shaft, the gear having a large hub for this pur- Specification of Letters Patent.

ing made loose longitudinally Within the hub, so as to perform the function of a slip-joint, relieving thereby the necessity of the exact maintenance of centers or distances between the axle center and the plane of the oblique gear driven by the motor shaft. The gear B is mounted in a suitable support B and engages a gear on the motor shaft A.

Connected with the sleeve B is a driving or propelling g'ar C engaging'the rack K, see Fig. 1 and this gear or sprocket is so mounted as to be movable so as to yield or move free of the car to accomodate itself to the inequalities of the rack as the car moves there-along that is, so as to form a swiveling propelling gear. As shown in Figs. 1 and 2, this driving gear or sprocket is SWIY? oled onto the sleeve B said sleeve having a ball I which fits into the hub of the gear C. This gear is provided with resilient means for guiding it. As shown in Figs. 1 and 2, for exaIuple,--th is resilient means consists of opposed engaging'devices-D, whicl rarc elastically pressed together in any desired 1nanner,--as by means of the spring D. -The movement of these parts is limited by the stops A number of these guiding devices may be used to engage the gear at different points at angles" to each other, asshown in Fig. 4.

The drivinggear C, in Figs. 2, 3, 4, 5 and 9, are shown as being insulated the rim from the hub, by the insulation C shown clearly; in Figs. 2 and 5. This is for the purpose of adapting the present construction to the class of third and rack-rails, where the rack is employed as the electric conductor between the source of electrical supply and the motor. In this instance, the guide or device for guiding the swiveling propelling gear may be used for the conductor, as is illustrated in Fig. 2 the current being taken off by the engaging devices D.

In the arrangement shown in Figs. 1 and 2, for 0X- amplo, the tilting action of the gear takes place about ihc m-nlr-r of l-lH goal. This lihing acti n may be 1 curcd by other arinng'cmcnis, such for example as shown in Figs. (i, 7, S and f). in Figs. ii, 7 and S, the gear is swiveled about a pivot E connected with the body of the car or locomotive, or some other part associated therewith, said gear being mounted in the swiveled bracket E, as illustrated in Figs. 6 and 8. In this construction, the gear B is connected with the shaft carrying the gear C and is engaged by the gear 13 connected to the driving shaft B and gear B which connects with the armature shaft. It will be seen that by this arrangement the driving gear or sprocket C is, free to tilt or move or oscillate with relation to the car and. without moving the body of the car, and thus an automatic adjustment is made for inequalities and misalinements of the rack.

In Fig. 9, the driving gear or sprocket C is mounted pose and the part B contained within the hub and be-- a shaft carried by a frame F, which is pivotally engaging the rack.

suspended from the body of the car, as by being mount- 1 ed upon the projecting shafts or axles 1" journaled in i hearings on the body of the car. In this case, the gear oscillates or swivels about centers in a lower plane than when constructed as shown in Figs. (3, 7 and 8. In

every instance, however, it is desirable that this swiv cling or tilting action takes place preferably about a center which is coincident or practically coincident with the plane of the gear. A clutch device is shown between the sprocket and the car axle, so that the sprocket may be connected with or disengaged from the car axle at will and which acts as a torque transmitting connection between the gear and the car wheel.

The sleeve 13" is free from the car wheel normallyand is connected thereto by the clutch device I. It will thus be seen that I have here an arrangement by means of which the driving sprocket may follow the inequalities of the rack rail, without communicating the eccentric or undesirable motion to the body of the locomotive or car.

I have described in detail particular constructions embodying my invention, but it is of course evident that the parts may be varied in many particulars and some of the parts omitted and others used with parts not herein shown, without departing from the spirit.

of my invention, and I therefore do not limit myself to the constructions shown. I
